+/**
+ * Our config parser.
+ *
+ * Each parser is responsible for creating discover_boot_options from config
+ * files found on new devices. The boot items discovered during parse will have
+ * 'resources' attached (see @discover_boot_option), which may already be
+ * resolved (in the case of a device-local filename, or a URL), or unresolved
+ * (in the case of a filename on another device).
+ *
+ * If the boot option contains references to unresolved resources, the
+ * device handler will not inform clients about the boot options, as
+ * they're not properly "available" at this stage. The handler will attempt to
+ * resolve them whenever new devices are discovered, by calling the parser's
+ * resolve_resource function. Once a boot option's resources are full resolved,
+ * the option can be sent to clients.
